Installation Overview
Once you have everything you need, let’s get started!

Thermostat Installation
Turn OFF power
Turn off all power to your
HVAC (Heating, Ventilation,
and Air Conditioning) system
by using the master
equipment switch or
circuit breaker box.
Confirm that your system is off
Try to adjust the temperature on your old thermostat. If
you don’t hear the system turn on within 5 minutes, air
does not come out from the vents or the old thermostat
does not even power on, then you have successfully
turned off the power to your system.
Step 1 Step 2
Make sure your
old thermostat
Does Not Contain
Line Voltage Wiring
If you see any of these wire nuts,
unfortunately the BCC50 will not work
with your system. If you are unsure or
would like to discuss your options,
please contact a professional or our
support line: 1-800-283-3787.
Step 3
WARNING: Failure to turn off the power may
result in electrical shock and/or damage to the
equipment.
Remove the old thermostat from the
old wall plate

Take a picture of the existing wiring
Make sure that you can clearly read the terminal labels and
see which wires are connected to which terminal from your
photo. You will need to reference this
photo later during the initial setup.
Note: You can also use the wire labels
we have provided you to correctly
label each wire based on the terminal
where it is connected.

Confirm you have a C-wire connected
to your old thermostat wall plate
If you do not have a C-wire connected to your old
thermostat, please contact a professional or our support
line for further assistance to determine if the BCC50
Thermostat is compatible with your system.

Disconnect the wires from the old thermostat and
remove the wall plate using a screwdriver
Some thermostats will also require you to use a screwdriver to
disconnect the wires. After the wires are disconnected and
the wall plate removed, we recommend wrapping a pen or
pencil around the wires to prevent them from falling back into
the wall.
Step 6
Step 7
Note: If the new Wall Plate
does not cover up any
holes or unpainted spaces
left by your old thermostat,
use this opportunity to
patch any holes and paint.
Pull thermostat wires through the hole in the center
of the BCC50 wall plate and mark the location of
the mounting screws
It is recommended to use the BCC50 Wall Plate as a reference
guide to mark the mounting holes and ensure that
all holes and unpainted
surfaces are covered.
8
Drill and insert wall anchors (if necessary)
Drill two 7/32” holes where you marked the location of the
mounting screws and then insert the wall anchors provided
into these mounting holes.
Check if the wall plate is level and insert screws
Make sure your new BCC50 wall plate is level and insert the
included screws from the package and mount your new wall
plate to the wall using a Phillips head screw driver.
Step 8 Insert each wire into the corresponding
terminal and close each terminal using a
flat head screw driver
Use the image you took with your
smartphone of your old thermostat wiring
or the wire labels as a reference for where
to place each wire. Be sure that you insert
each wire, one by one, and then
immediately close the terminal and confirm
that the wire is secure inside the terminal
before moving to the next wire. Repeat this
process for each wire to be installed. If you
are unsure of the terminal names on the
BCC50 Wall Plate, refer to BCC50 Terminal
